The data blocks are stored in 4 second frames. I was wondering if there is a 4 second delay before the first set of data is even stored to the chip. This was stored all on a chip and the data stream for a 4 second frame takes 4 seconds to steam to the storage system.because the data is not stored directly to the tape, its stored in a buffer while its being written, someone here has said that results in a delay of up to 3 seconds
i assume the FDR data is stored on magnetic tape, this takes the longest amount of time to write to
and how do you conclude that given that the FDR data didnt record that far?
This is from reading about the FDR recorder used on 77 type aircraft.
